Part Number: AM5708
Hello TI
Our circuit board has been modified in hardware to have a DDR capacity of 512M, but now it has been replaced with a 1G capacity. My modifications are as follows:
board/ti/am57xx/board.c
static const struct emif_regs beagle_x15_emif1_ddr3_532mhz_emif_regs = {
.sdram_config_init = 0x61851B32,// o
.sdram_config = 0x61851B32,// o
.sdram_config2 = 0x08000000,
.ref_ctrl = 0x000040F1,
.ref_ctrl_final = 0x00001035,
.sdram_tim1 = 0xcccf36ab,
.sdram_tim2 = 0x308f7fda,
.sdram_tim3 = 0x409f88a8,
.read_idle_ctrl = 0x00050000,
.zq_config = 0x5007190b,
.temp_alert_config = 0x00000000,
.emif_ddr_phy_ctlr_1_init = 0x0024400b,
.emif_ddr_phy_ctlr_1 = 0x0e24400b,
.emif_ddr_ext_phy_ctrl_1 = 0x10040100,
.emif_ddr_ext_phy_ctrl_2 = 0x00910091,
.emif_ddr_ext_phy_ctrl_3 = 0x00950095,
.emif_ddr_ext_phy_ctrl_4 = 0x009b009b,
.emif_ddr_ext_phy_ctrl_5 = 0x009e009e,
.emif_rd_wr_lvl_rmp_win = 0x00000000,
.emif_rd_wr_lvl_rmp_ctl = 0x80000000,
.emif_rd_wr_lvl_ctl = 0x00000000,
.emif_rd_wr_exec_thresh = 0x00000305
};
By checking EMIF_SDRAM_CONFIG There is no problem with the configuration of the CONFIG register. However, the size of my DDR is only 512M.
How can I modify the DDR size ?
